This key permits a flush grippingwheel be knurled or roughened as indicated. These construction so thatthe tool is capable of use as indicated in Figure 4 on even the shortestof studs or dowels.

In use, the tool will be applied over the stud, as shown in Figure 4,with the stud engaged in whichever aperture I4 or I5 is the mosteffective depending on the diameter of the stud and then a wrench willbe applied to the socket l2 and turned in a direction counter to that atwhich the stud was threaded into the block from which it is to beremoved, which first turns the gripping wheel I1 so that its periphery Hgrips the stud between it and the opposite wall of an aperture l4 or [5.Continued rotation of the wrench l3 will turn the block I0 and the studgripped therein and will thread the stud out of the socket in which ithas been threaded.

Modifications of the invention may be resorted to Without departing fromthe spirit thereof or the scope of the appended claims.

What is claimed is:

1. A stud remover comprising a block formed with two adjacent aperturesof different sizes for receiving studs of various sizes, the bottom ofsaid block being recessed, a shaft rotatably extended through saidblock, said shaft having eccentrically secured on its bottom end agripping wheel, the lower face of which is substantially flush with thebottom surface of the block, the spacings of said apertures with respectto the axis of said Wheel and the proportions of the wheel being suchthat the wheel may be turned on its. axis to grip studs or the like ofvarious sizes in either of said apertures against portions of the wallsthereof remote from the axis but permitting the wheel to be turned to aposition in which it.

clears both apertures, and means on said shaft at the top of said blockfor rotating said shaft relative thereto to move said wheel to grip astud in either of said apertures against said remote portions thereofand by continued rotation of the shaft to turn said block so as to turna stud gripped in the block.

2. A stud remover comprising a block formed with two adjacent aperturesof different sizes to provide relatively fixed jaws for receiving studsof various sizes, a shaft rotatably extended through said block, saidshaft having eccentrically secured thereon a gripping wheel, thespacings of said apertures with respect to the axis of said grippingwheel and the proportions of the wheel being such that the wheel may beturned on its axis to grip studs or the like of various sizes in eitherof said apertures against portions of the walls thereof remote from theaxis but permitting the wheel to be turned to a position in which itclears both apertures, and means on said shaft for rotating the samerelative to said block to move said wheel to grip a stud in either ofsaid apertures against said remote portions thereof, whereby continuedrotation of the shaft will turn the block so as to turn a stud grippedtherein.
